WEATHER-STRIP.

Specification of Letters Patent.

Patented May 22, 1906.

Application filed January 10, 1906.- Serial No. 295,405-

To all whom it may concern:

Be it known that I, ED\VARD F. SHEILA- BERGER, a citizen of the United States,-resid ing at Dekalb, in the county of Dekalb and State of Illinois, have invented certain new and useful Improvements in WVeather-Strips, of which the following is a specification.

My invention relates to weather-strips for Windows, and has for its object to provide a simple, economical, and easily constructed and applied Weather-strip, avoiding special construction of the sash 0,1 window-casi1ig for its application. These objects I attain by the device of the present invention, which consists, essentially, of a transversely-flexible metal strip of shallow channel form' throughout and having a narrow rounded head on its outer surface coincident with its axis, which. strip is secured through said head to the bottom wall of the usual guide-groovc of the window-casing and slidably contacts at its margins the adjacent edge of the sash stile inwardly of the corners of the latter.

My invention will be readily understood in connection with the accompanying drawings,

Wherein- Figure 1 is an elevational view of a fragment of the weather-strip, and Fig. 2 is a transverse sectional view through one stile of a window-sash and the cooperating guide groove of the window-casing.

, Referring tothe'drawings, 5 designates a fragment of the window-casing, to whicn is secured the usual guide-strip 6 and parti1ig-' strip 7, these latter, with the casing member 5, forming the usual channcbguidc 8, in which slides the stile 9' of a window-sash.

1O designates a thin metal weather-strip of some elastic or yielding material, copper. having been found in practice well adapted for the purpose of the present invention. This strip has a slightly-curved. orchannelshaped form in cross-section, as seen in Fig.

2, and has formed on its outer or convex surface and coincident with its longitudinal axis a rounded bead 11, conveniently formed by pressing the. metal outwardly by stamping -or;otherwise. The strip thus formed is preferably secured to the inner or bottom wall of the guide-groove 8, as by means of tacks or light screws (indicated at 12) passing through holes or punctures 13 in the head 11, and the" opposite n'iargins of the strip slidingly engage the adacent edge of the sash 9 with a slight friction sufficient to make a snug sliding fit, depending upon the thickness of the strip and the resiliency of the material of which it is composed.

It will be observed that the head 11 and the manner in which the strip is secured to the casing provide for and permit the strip to have a slight transverse oscillating or rock ing movement, whereby the continuous engagement of the margin of the strip with the edge surface of the stile is insured, even thougl the latter be somewhat warped or otherwise irregular.

While I have shown and described the strip as secured to the inner wall of the casing-groove and slidably engaging the stile, it evident that this might be reversed and the strip secured to the edge of the stile and slidably engaging the bottom wall of the groove within the spirit and purview of the invention. It will also be observed that the syn1 metrical form of the strip permits it to be applied either end up, and also provides virtually a double seal against the passage of dust, moisture, cold air, and the like between the sash-stile and the casing.

I claim T hecombination with a casing having a guide-groove, and a sash-stile having a plane edge throughout, of a transversely-flexible metal strip of shallow channel form throughout and having a narrow rounded bead on its outer surface coincident with its axis, said strip being secured through said bead to the .bottom wall of the guide-groove and slidably contacting at its margins the adjacent edge of the stile inwardly of the corners of the latter, substantially as described.
